Product Review/Suggestions:The Everlasting Treat Balls and Fire Plug toys are some of the best, virtually indestructible toys available that help solve the most common cause of canine behavioral issues - boredom. Stuff these interactive toys with the dog’s kibble and allow them to hunt for their food, which is an exercise innate to any dog. Make the toys more challenging by putting the Everlasting Treats on one or both ends with the dome up or the dome down. Put peanut butter or wet dog food inside the toys and freeze them for a trickier hunt, and then wash them out easily in the dishwasher. The options are endless and the physical and mental stimulation given to your dog is invaluable. Behaviors such as destructive chewing and nuisance barking will begin to diminish rapidly.
